Overview
The MAX5702BAUB+T, produced by Analog Devices Inc./Maxim Integrated, is a ultra-small, dual-channel, 12-bit digital-to-analog converter (DAC) with buffered voltage outputs. This device is part of the MAX5700/MAX5701/MAX5702 family and is designed for low-power and low-voltage applications. It features an internal reference that can be software-selectable to 2.048V, 2.5V, or 4.096V, and it operates over a wide supply voltage range of 2.7V to 5.5V with extremely low power consumption of 1.5mW. The MAX5702BAUB+T is available in a 10-pin µMAX and an ultra-small 10-pin TDFN package, making it ideal for space-constrained designs.
